How to magnify your screen with zoom for visual accessibility on your iPhone or iPad

Zoom is an Accessibility feature that makes everything from text to icons to interface elements bigger and easier to see on the iPhone and iPad. Zoom magnification defaults to 200% but can be set from 100%-500% to help anyone with low vision of any level. When in zoomed mode, all the standard navigation and selection gestures — tap, swipe, and pinch — work just like normal. Zoom can even work alongside VoiceOver to provide even greater assistance for those with visual impairments.

Note: Designers use zoom as well to help check pixel-level details on-screen.

How to enable zoom for better visual accessibility on your iPhone or iPad

Launch the Settings app on your iPhone or iPad.

Tap on General.

Tap on Accessibility.

Under the Vision section, tap on Zoom.

Turn the Zoom option On.

Once you've got Zoom enabled, you can use it on the fly. Here's how to use it:

Double tap with three fingers anywhere on the screen to enable and disable zoom. You can do this from pretty much anywhere.

Drag three fingers around the screen to pan around and move to another area of the screen.

Use one or two fingers to scroll in the particular section that is on the screen.

That's it! You're good to go! If you ever decide you don't like zoom enabled, you can easily disable it by hopping back into the Settings app again.

It should work depending on which os you are using, in earlier version you could not use voice over and zoom at the same time, I am not for sure but I think all versions had some zoom capability check my post below for a little further use.

This is great for people like my dad who have poor eyesight; however, he gets by by dramatically increasing the font size. If I recall, this doesn't work with Safari or other browsers, so I might show this to my dad anyways.

on the second tap with three finger slide up to enlarge and slide down to decrease zoom. Wherever you have zoomed out with the three finger double tap and slide is where the next double tap will zoom to.
